Detailed Description

Zero-initialize this struct before use, then fill in exactly the sub-config needed by the model family you want to run.

Exactly one model family should be configured for each recognizer. For example, set only one of transducer, paraformer, nemo_ctc, whisper, tdnn, sense_voice, moonshine, fire_red_asr, dolphin, zipformer_ctc, canary, cohere_transcribe, wenet_ctc, omnilingual, medasr, funasr_nano, fire_red_asr_ctc, or qwen3_asr.

If multiple model families are configured at the same time, the implementation will choose one of them, and which one is used is implementation-defined. Do not rely on any precedence rule.
